SL-668 - (Premium Grade) Hydrophobic Single-Component PU Foam Waterstop Agent
SL-669 - (Premium Grade) Hydrophilic Single-Component PU Foam Waterstop Agent

SL-668 (Hydrophobic MDI-based Polyurethane)

A hydrophobic polyurethane based on MDI, featuring zero water absorption and no shrinkage.
Single-component packaging. Reacts with water to form an impermeable urethane structure. It will not corrode or damage RC (Reinforced Concrete) structures or steel reinforcement.
Excellent toughness. Suitable for use in areas with potable water contact.
Compatible with single-component injection equipment.

SL-669 (Hydrophilic Single-component Foaming Polyurethane)

This product has a low viscosity, preventing clogging in high-pressure injection hoses due to increasing viscosity during application. It is easy to use and offers excellent workability.
Exhibits excellent water miscibility, minimizing residual water within cracks. Prolonged presence of water can damage the foam structure and cause secondary leakage.
High reactivity: reacts with water and completes curing in approximately 20 to 120 seconds.
Excellent stability: remains functional within the application window after opening. Unopened product can be stored for more than six months without deterioration.
Strong adhesion to concrete, ensuring no delamination or separation from the concrete surface.
Capable of reacting with water sources ranging from slightly acidic, slightly alkaline, to even seawater, without compromising the physical and chemical properties of the foam.
High structural strength and toughness, providing long-term water resistance.
